ACCUTRACK Speedometer II

This Speedometer to help set up speed-matching of locos with SPROG.

Programmable for N or HO, this unit stands over any track, and displays the speed of a train as it passes, in either direction. It is a stand-alone device, and runs off two AAA batteries, included in the package, so is ideal for DC or DCC layouts.

The speedometer uses the precision of a microcontroller to measure the time between two infrared beams that the train passes through. Based on this time, the scale speed can be calculated from a mathematically derived calibration factor. Built into the software are the calibration factors for N & HO scales, and these factors are selectable from a button accessible from the front panel of the device.

Speed is displayed for 5 seconds and then unit goes into power saving mode.
Auto shut off after 5 minutes of no trains.

    • HO scale
